Interaction of Math Symbols

Hi guys. I am working now on my very first app - small math game.

Screens with UI are coming soon. And now I am trying to find interesting interactions betweens math symbols - plus, minus and multiplication.

Do you have better ideas of animate interactions? Lets rebound! :)

AE project is available to download.

You can read more about wip of development of this app in my blog (in russian language).
